Abstract
Solar energy systems use concentrating optics with photovoltaic cells for optimizing the performance. Advanced concentrators are designed to maximize both the light collection and the spatial uniformity of radiation. This is important because irradiance uniformity is critical for all types of photovoltaic cells. This is difficult to achieve with traditional concentrators, which are built with polished optical surfaces. In this work we propose a new concept of solar concentrator which uses small diffuser segments in key points to increase the irradiation uniformity. We experimentally demonstrate this new concept by analyzing the effects on both efficiency and irradiance uniformity due to the incorporation of scattering ribbons in a compound parabolic concentrator.
